Abstract
The invention provides an electric vehicle charging device composed of a metal fuel cell. The electric vehicle charging device comprises a shell and a displayer, an alarm and a control panel which arearranged on the shell, and a DC / DC converter I, a DC / DC converter II, a cell management and control system, a monitoring and controlsystem, a starting cell and N metal fuel cell stacks which are contained in the shell; each stack is connected with the cell management and control system through a measurement and control line; the electric energy input end of the DC / DC converter I is conductivelyconnected with the electric energy output end of the stack, and the electric energy output end of the DC / DC converter I is conductively connected with a charging connector; the electric energy input end of the DC / DC converter II is conductively connected with the electric energy output end of the stack, and the output end of the DC / DC converter II is conductively connected with the monitoring andcontrol system and the cell management and control system; and the starting cell is conductively connected with the monitoring and controlsystem and the cell management and control system. The electric vehicle charging device is simple and fast in operation and safe and environment-friendly in operation.
Description
technical field [0001] The invention belongs to the field of electric vehicles, and in particular relates to the structure and operation mode of an electric vehicle charging device composed of metalfuel cells. Background technique [0002] With the depletion of fossil energy and the strengthening of environmental protection, it has become the development direction of the automobile industry to develop green, safe and efficient electric vehicles to replace traditional fuel vehicles. At present, commercialized power batteries for electric vehicles mainly include lead-acid batteries, lithium-ion batteries, and nickel-metal hydride batteries. Although electric vehicles have been used at present, electric vehicles powered by lead-acid batteries, lithium-ion batteries, nickel-metal hydride batteries, etc. have short cruising range and long charging time, which cannot meet the needs of many applications. In addition, the coverage of charging piles for charging electric vehicles i...
